Include paths

Posted on 1998-06-05

I'm using g++ to compile OpenGL apps, but because our system doesn't have GL I had to compile and install it into my user directory. The problem is that although the -L option works OK for the libs, I can't specify the path to the include files which need to be called as <Xm/Xm.h> or <GL/gl.h> in the code to be portable to my home linux system.

I've tried doing "-Ipath" and "-I- -Ipath" in the Makefile as it says on the man page for g++, but the compiler still can't find the includes.

Thansk for any help,

You have to set your include path to one directory above the Xm.h and gh.l files.  You also may need to use multiple include paths, e.g., /foo/bar;/googoo/gigi;/and/another/one.

laeuchli, locking the question before providing a valid answer is EXTREMELY bad form and usually results in complaints to EE administration.

Sorry, but I thought it was a good practice. I have seen many experts do it so I thought it was ok. Well sorry.

Not really.  Most of the experts that lock a question before providing an answer follow up with a really long and detailed explanation in a comment after 5-15 minutes (which is the time that takes them to type it in an organized way).

jhubbard, I don't know what the behavior of the "-I" argument of your compiler is but I guess it is cumulative.  In that case try: "-I<path-to-GL> -I<path-to-Xm> ..."

Thanks, I just found out that this system actually has OpenGL, but hidden in some obscure and arbitrary directory. You'd think experienced sysops could organise where to put libraries, but noooo......

Oh well, thanks anyway.

You could have gotten your points back (since you found the answer yourself).  Too late now...
